Onsen (hot springs) typically have varying operating hours depending on the location and facility. However, it’s common for Japanese hot springs to open in the morning around 9:00 am or 10:00 am, with closing times ranging from early evening to late night.

Here are some general timeframes you might find:

  • Early risers may want to visit between 8:30 am and 12:00 pm.
  • The main operating hours often fall within the 1:00 pm to 5:00 pm range.
  • Some hot springs with extended hours may stay open until 7:00 pm or even as late as 9:00 PM.

Of course, it’s always best to check the specific onsen you plan to visit for their unique operating schedules.
